HELLO it sounds like a couple of things could be wrong. you could have what they call a dry socket or a bad, cold solder joint. what it means is that on the power supply section of the chassis the tv has gotten so hot that the solder has melted away frrom its connection and it is not making true contact on the chassis. if you know how to solder you can fix this yourself.. you will need some 60/40 rosin core solder and a soldering gun that is not over 40 watts. you will need to go over the connections on the chassis in the power supply section. hope this helps you just remember you must unplug your set before working on it. GOOD LUCK

The power on no piture


If the power light comes on (green) for a few seconds and goes off:

MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(input) and "menu" buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC's is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

I have a mitsubishi 1080 series tv. I turned the tv off and then I went to go turn it on, now the little green light on the tv stays on for 2 sec. and then goes away without the piture ever coming on.


A hint--if the green power light comes on for a few moments and goes off do the self check this set has.

On the front of the set press and hold BOTH THE MENU AND INPUT (OR DEVICE) BUTTONS BOTH FOR AT LEAST 5 SECONDS. Release both buttons and look at the power button.

If this is the case the power light will blink a two digit error code--most common in this case is 2 blinks, a pause and 2 blinks--it will repeat the code up to ten times.

Let me know if you find an error code or the power light just blinks and never stops.

If this helped you rate this solution as I do this here for free.

When i switch my tv on. I can hera the volume but no picture. Then the tv switches off and restarts until both the volume and picture is working. This could take up to an hour


yes. tv has a circuit which controls current to the red, green, and blue piture tubes. you wont get picture until they are balanced. adjust the screen controls until it comes on faster. it should only take maximum 20 seconds for a picture. gaurantee it will fix it. adjust the screen control

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

My tv goes blank with sound only.


tough call. from your decription it could be the tubes the pulsating. but if i had it in the shop i wwould first look at the convergence curcuit. the fact that the on screen display come up in colors inidcates convergence problems. you might have multiple component falure there. as for cost it could be diddicult to say. average repairs like this barring piture tube problem at my shop run 200 labor and about 150 parts. this is just for convergence cuircit rpair
